2. Auto Setting Mode (ACSKAD/ACSKDA bit = “1”)
When the ADC and DACs are connected to each PORT placed in Auto Setting Mode, MCLK frequency is detected
automatically (Table 26) and the internal master clock is set to the appropriate frequency (Table 27). In this mode, the
setting of DFSAD, DFSDA1-0 bits are ignored.
